Application filed July '7,

a citizen of the Republic of France, and resident of 11Rue du Printemps, in the clty of Paris, Republic of France,. commercial agent, have invented an Improved Ingot- Mold, of which the following is a full, clear,

This invention relates to rotary molds. By means of such a mold rapidly rotatedthe metal is'subjected to centrifugal pressure, with resulting increase of density and cohesion, causing homogeneousness if the metal be single and thorough mixture of elements throughout the mass in the case of an alloy. These advantages are especially important in the latter case, since there is often great heterogeneousness in the different parts of a mass of alloy composed of elements which vary ,,widely in their densities and melting points; also these divergencies tend to separate the. molecules of the said elements, so that the lighter kind'of metal will tend to float above the heavier, and the mass as a whole will lack homogeneousness and equality of resistance and elasticity in its various parts.-

The said invention consists chiefly in certain improvements in the construction of the mold and in its means of supply, as hereinafter more particularly set forth and claimed.

The shape of the mold and its inner cavity of course must vary to suit the form of the article to be cast. In the accompanying drawings I have illustrated a cylindrical ingot mold having a horizontal'axis and of thickness much less than its diameter.

In said drawings Figure 1 represents a side elevation, part y inlongitudinal vertical section,of mechanism embodying my invention; and Fig. 2 represents an end elevation of-the same.

A shaft 2, mounted in bearings 12, and provided with belt pulleys 13,.carries at one end an integral disk or circular plate 1 of metal, constituting the rear wall of the mold. A similar metal disk or plate 7 is arranged parallel thereto constituting the front wall of said mold. A broad ring or short cylinder 5 is interposed between these parts, fittinginto grooves or annular recesses6 and 9 of the same, which recesses have their outer parts vertical andtheir inner parts inclined to taper Inward as shown in Fig. 1.

the peripheral part of plate or disk 7 and which receive nuts 11 outside of said lugs and are pivotally attached at their other ends to studs 4 on lugs of plate or disk 1. These bolts hold the parts 7 and 5 to part 1 and permit the ready removal of the former two.

In the center of plate 7'an opening8 is provided, recelvinfi the outlet end of spout or nozzle 14, whic discharges metal within the mold. Thisspout is pivoted near its middle between bifurcations 16 on the upper end of a supporting standard, the pivoting belng between a lug on the inner face of one of said bifurcations and the rounded end of an ad uSting screw 15, which works through the other bifurcation at an opposite point. This screw may be tightened or loosened by a handle 17. The lower end of said standard is also Bifurcated and it is pivoted by bolts 18 to fixed lugs, in order that it may be lowered at will, after the removal of a locking bolt 19, which holds it in its normal upright The spout may be withdrawn from the mold by loweringthe su port as thus stated; or it can be separated fiom the support by removing or suitably loosening screw 15 .and lowering the support without it. Screw 15 enables the angle of the spout to be varied within certain limits in order to discharge the metal ,to the best advantage. As a rule it is desirable to discharge near the axial line of the mold for keeping oxidation and spraying of the'metal at a minimum by avoiding the currents of air in the rapidly rotating mold between its center and its periphery. The rotation is of course communicated to the shaft and mold through ulleys 13, or one of them, with the deslred degree of rapidity. The centrifugal force thereby applied to the rotating mass of metal forces it against the inner face of ring or cylinder 5 and the proximate parts of plates 1 and 7. This pressure makes the mass more compact and homogeneous, being analogous in its effects to kneading dough. The axis of rotation is not necessarily horizontal as shown and it is, not necessary to give the mold a cylindrical form; but this arrangement and this shape are well adapted to suaccessful casting, with the advantages state Patented Oct. 6, 1914.

I claim as new and desire to secureby Letters Patent is:

1. A rotary mold having an inlet opening for molten metal, in combination with a spout normally extending into said mold through said opening, a pivoted support for said spout adapted to be turned down withdrawin said spout from said mold and a remova le fastening device for holding said support and spout in their normal position.

2. A rotary mold having a central open-,

ing for admission of molten metal, an -inclined spout extending into said mold through said opening, a support for said spout and means for attachmg said spout pivotally and adjustably to said support, thereby regulating such inclination.

3; A rotary mold having a central opening for the admission of molten metal, an

inclined spout extending into said mold through said opening, a pivoted support In wltness whereof I I have hereunto set my hand in the presence of two witnesses.
